Crashlytics addresses a huge hole in mobile app development: deep insights into an app’s performance to pinpoint and fix issues quickly and easily. Built by a hardcore team, Crashlytics is the most powerful, yet lightest weight crash reporting solution. We find the needle in the haystack, even the exact line of code that your app crashed on, so you can quickly scan and trace an issue. Crashlytics has been deployed in hundreds of millions of devices and powers thousands of today’s top applications, including Twitter, Square, Yammer, Yelp, and GroupMe.
